Film capacitors, also known as plastic film capacitors, are ceramic-based capacitors, utilizing a film composed of polypropylene or polyester between two metallic plates to maintain a charge between two levels. This type of capacitor has high dielectric strength, high insulation resistance, low cost, and good temperature stability. The product model MKP385310125JFI2B0 (hereinafter referred to as the MKP capacitor) is a metallized polyester film capacitor which is suitable for general AC power transmission and signal transmission applications. This capacitors is specially designed for use in HVAC, lighting, and industrial systems where high frequency and temperature performance are required.

Application Field

The MKP capacitor is mostly seen in industrial applications as it provides higher insulation resistance and voltage capabilities than plastic film capacitors. It is widely used in DC link circuits, power factor correction circuits, power supplies, and lighting systems. It is also employed in electronic ballasts, damping circuits of negative feedback amplifiers, and circuits for controlling medium- to high-voltage applications. Moreover its excellent electrical properties enable it to be used in thin-film circuits as well. The MKP capacitor is also suitable for ultrasound welding, welding equipment, machine tool controllers, inverters/converters, motor control circuits, motor start/stop circuits, small motor drives, electric welding machine and rectifiers.

Working Principle

The MKP capacitor works by exploiting a conventional electrostatic attraction process. The capacitor consists of two metal plates, covered by a thin layer of insulating material. This insulation material is called the dielectric, and this dielectric material is what is used to maintain a charge between the two plates. When an electric current, such as from a battery or mains power, passes through the capacitor, it causes an electromagnetic field to build between the two metal plates.

This electromagnetic field causes the charges to be either repelled or attracted, depending on the polarity of the charge. This creates an electrostatic attraction between the two plates, which results in the buildup of a charge between them. This charge then acts like a barrier to the flow of current, and thus can be used to store the charge and regulate the current.

Conclusion

The MKP385310125JFI2B0 is a type of metallized polyester film capacitor, which is mostly used in industrial applications. It has high dielectric strength, high insulation resistance, good temperature stability, and is especially suitable for applications where high frequency and temperature performance are required. The MKP capacitor works by employing an electrostatic attraction process, where an electromagnetic field is generated by an electric current, causing the charges to be repelled or attracted, creating an electrostatic attraction between the two plates.]
